Peter O'Brien will enter spring training next year as a catcher.
O'Brien expressed a desire to move back behind the plate after spending the 2015 season trying out corner outfield. The 25-year-old has a big bat, but he was never a very good defensive backstop and how he fits into the Diamondbacks' future plans is currently unclear. Welington Castillo should open the 2016 season as Arizona's starting catcher. Mon, Oct 5, 2015 02:17:00 PM

Peter O'Brien homered off Dallas Keuchel in his lone at-bat off the bench Friday against the Astros.

It seems crazy that the Diamondbacks haven't given O'Brien a single start since his callup on Sept. 8, but it likely has a lot to do with his unsettled position situation. The team is again looking at making him a full-time catcher, even though he's never going to be very good back there. His bat remains intriguing. He's had just seven plate appearances since his callup, but he's 3-for-5 with two walks. It seems like the Diamondbacks really blew it by not giving him some starts in left.

Peter O'Brien has told the Diamondbacks that he wants to return to the catcher position.

O'Brien had the yips when trying to throw the ball back to the pitcher earlier this season and eventually moved to the outfield. He doesn't think it will be an issue anymore, though, and he and the D'Backs would both like him to take another crack at things behind the plate. O'Brien would certainly make for a much more interesting prospect if he can stick at catcher.

The Diamondbacks would like Peter O'Brien to return to the catcher position next season.

O'Brien developed the yips when trying to throw the ball back to the pitcher earlier this season and eventually asked for and was granted the opportunity to move to the outfield full-time. However, it appears the D'Backs still want to develop him as a catcher. It's certainly understandable, as his bat would carry a lot more value behind the plate. That said, Arizona won't force a move, as manager Chip Hale said O'Brien's choice of position is "up to him." O'Brien batted .284/.332/.551 with 26 home runs and 107 RBI at Triple-A Reno this season.

Making his second career appearance as a pinch-hitter, Peter O'Brien singled in a run in his lone at-bat Saturday.

It's the same thing he did Friday, so he's 2-for-2 to start his career. Ideally, the Diamondbacks would get him some starts in the outfield down the stretch. However, it's going to be tough to accomplish with David Peralta, Yasmany Tomas and Ender Inciarte currently occupying the corners.

Diamondbacks purchased the contract OF Peter O'Brien from Triple-A Reno.

O'Brien, who is strictly an outfielder at this point, batted .284/.332/.551 with 26 home runs and 107 RBI over 131 games this season in Triple-A. The power is intriguing, but his approach is a work in progress. It's unclear how much he'll play down the stretch, but it should be a fun sneak preview for D-Backs fans.

Diamondbacks general manager Dave Stewart said Monday that a decision has not been made as to whether prospect Peter O'Brien has given up catching and become a full-time outfielder.

The Triple-A Reno Aces' official Twitter account tweeted Sunday that O'Brien had "made the decision" to give up catching and it was later confirmed by the D'Backs. The tweet has since been deleted and now Stewart is saying nothing is final yet. "We're never going to let a player dictate to us what he wants to do," Stewart said. "We'll sit down and, as a group, discuss and talk about what we should be doing and what the best direction is for a player." O'Brien's throwing from the catcher position has returned to normal after he had the yips in spring training. Still, it sure seems like his future is in the outfield even if the decision isn't official yet. He's batting .339/.377/.634 with 12 homers and 47 RBI over 49 games for Reno this season.

The Diamondbacks confirmed Sunday that prospect Peter O'Brien has switched to the outfield full-time.

Given the D'Backs injury woes behind the plate, and the fact that O'Brien had been making strides defensively, it's a surprising development. The 24-year-old is currently hitting .341/.382/.653 with 12 homers and 46 RBI over 46 games at Triple-A Reno.

Diamondbacks prospect C/OF Peter O’Brien went 3-for-4 with a home run and double on Monday for Triple-A Reno.

The home run and double were his fourth and fifth of the season, respectively, and he also plated two in the game. He’s batting .404/.429/.766 (.429 BABIP) with 14 RBI and nine strikeouts (but no walks) through 49 plate appearances. O’Brien, 24, entered spring training high on Arizona’s depth chart behind the plate, but he was plagued by a case of yips when throwing the ball back to the pitcher and has since moved to the outfield. He’s seen time at both corner outfield positions at Triple-A Reno (more in left field, though) and, unsurprisingly, is already putting up big power numbers in the hitter-friendly Pacific Coast League.

Diamondbacks manager Chip Hale said Tuesday that prospect Peter O'Brien will continue to play the outfield at Triple-A Reno for the next month or so.

The plan is to then give him some work at catcher. O'Brien was moved out from behind the plate after having issues during spring training throwing the ball back to the pitcher. It hasn't affected his offense, as he's batting .391/.417/.609 with a home run over his first five games for Reno.

Diamondbacks catching prospect Peter O'Brien played the outfield in a minor league game for the second straight day Thursday.

O'Brien has had major issues this month in throwing the ball back to the pitcher, so the Diamondbacks are going to keep him away from the catcher position for the time being. "I think he's going to play some outfield (once the minor league season starts) and catching isn't out of the question, but we're still talking internally to figure out what's best for him," farm director Mike Bell said. The D'Backs were reluctant over the winter to pursue an upgrade at catcher mainly because they believed O'Brien would be ready to take over at the position in short order. Obviously, they didn't envision the 24-year-old developing a case of the yips. O'Brien was re-assigned to minor league camp earlier this week.

Diamondbacks reassigned C Peter O'Brien, INFs Danny Worth, Nick Evans, Danny Dorn and Jamie Romak and RHPs Jake Barrett and J.C. Ramirez to minor league camp.

O'Brien has far and away the most offensive potential of all the Diamondbacks catching options in camp, there are serious questions about his defensive ability behind the plate though. The 24-year-old slashed .271/.316/.594 with 34 homers and 74 RBI in 106 minor league games at High-A and Double-A in 2014.

Diamondbacks catching prospect Peter O'Brien is struggling with his return throws to pitchers.

According to Nick Piecoro of the Arizona Republic, there were more than a half-dozen return tosses that went wild Sunday in a "B" game. And the same thing happened in a Cactus League game Friday. It sounds like a case of the yips, though O'Brien does not carry a good defensive reputation overall. "I've been working on it," the powerful 24-year-old said Monday. "Getting it under control and making sure I keep the tempo of the game up and keep working from there."

Diamondbacks manager Chip Hale said Saturday of Peter O'Brien that he's "seen nothing that shows he can't be a frontline catcher in the big leagues."

"He's caught, he's blocked, he's received the ball well and he's thrown well," Hale added. Most scouts seem to think O'Brien won't be a long-term catcher, but the D'Backs have been adamant about him staying behind the plate. The 24-year-old is intriguing because of his power and could become the team's catcher sooner rather than later.

Peter O'Brien went 2-for-3 with an RBI single in a win over the Rockies Wednesday.

O'Brien is a highly touted catching prospect, and he got off on the right foot Wednesday. His RBI single in the sixth inning got the Diamondbacks on the board, and he finished with two hits on the day. With the D'backs trading away Miguel Montero over the winter, it's not out of the question that the 24-year-old could break camp with the club. His defense is still a work in progress but O'Brien slammed 34 homers in the minors last season, so his power potential is undeniable.
