Rustin Dodd of the Kansas City Star writes that Peter O'Brien "still faces long odds to make the roster, barring an injury."
O'Brien has slugged six home runs in 41 at-bats this spring, but he has two options left and the Royals are set to go into the season with Brandon Moss as their main designated hitter. The 26-year-old has big raw power and figures to get a shot with the big club at some point. Mar 19 - 1:11 PM

Peter O'Brien cranked his fifth home run of the spring Tuesday in the Royals' 8-4 defeat of the Angels.

It was a two-run shot off Angels right-hander Daniel Wright in the bottom of the eighth inning. O'Brien is making a strong case for a spot on the Royals' bench this spring. He has a 1.192 OPS in 31 at-bats.
Mar 14 - 6:56 PM

Peter O'Brien crushed his fourth home run of the Cactus League season as the Royals fell to the Athletics on Friday.

O'Brien entered the game as a pinch-runner, then tagged Nick Blackburn for a solo homer during a three-run uprising in the eighth inning. He now has four long balls and seven RBI during the spring and has probably done enough to secure a bench role on the Opening Day roster in Kansas City.
Mar 10 - 11:44 PM

Peter O'Brien launched his third home run of the spring Tuesday in the Royals' 6-3 victory over the Brewers.

He entered the game late as a defensive sub at first base and took Hiram Burgos deep for a two-run shot in the top of the eighth inning. O'Brien now has three home runs and six RBI through eight Cactus League at-bats as he tries to slide his way into the DH mix in Kansas City. Brandon Moss will be the primary option there to open the season, but he struggles against left-handed pitching. O'Brien is a right-handed hitter. Make the connection.
Feb 28 - 7:16 PM

Royals acquired 1B/OF Peter O'Brien from the Diamondbacks for RHP Sam Lewis.

O'Brien has flashed huge power numbers in the minors, but plate discipline has always been an issue and he doesn't fit well at any defensive position on the diamond. This move to the American League, where he can DH, should prove beneficial to his career. Though it's not like O'Brien has hit well in the majors up to this point, and Kansas City can be a tough place on power bats. Arizona designated the 26-year-old slugger for assignment in late December.
Jan 3 - 5:58 PM

Diamondbacks general manager Mike Hazen said that Peter O'Brien has drawn trade interest and is likely to be dealt.

O'Brien was designated for assignment a week ago, but it sounds like the D'Backs will be able to get something for him rather than lose him for nothing. Hazen said that both National League and American League clubs have inquired on O'Brien, who has great raw power but strikes out a ton and doesn't have a defensive home.

Diamondbacks designated OF Peter O'Brien for assignment.

O'Brien drew some buzz a few years ago as a catcher with power, but he no longer catches, strikes out at a high rate and has really struggled in his brief big league chances. Still, there's a chance some team takes a shot on the 26-year-old's raw power.

Diamondbacks recalled OF Pete O'Brien from Triple-A Reno.

O'Brien has five homers in just 67 career at-bats at the major league level, but that has come with a .164 batting average and .222 on-base percentage. The 26-year-old slugger will function as a bench bat.

Diamondbacks optioned OF Peter O'Brien to Triple-A Reno.

Nick Ahmed is back from the paternity leave list and will take his spot on the active roster. O'Brien batted .123/.167/.333 with four homers and a 25/3 K/BB ratio over 21 games with the big club.

Peter O’Brien slugged two homers and knocked in four runs in a 10-2 victory over the Phillies on Friday.

O’Brien launched a three-run homer against Adam Morgan in the fifth inning before taking Elvis Araujo deep for a solo shot in the seventh. The 25-year-old has just three hits in 19 at-bats with six strikeouts since being called up last Friday, but he has made them count, as all of them have been home runs. The all-or-nothing approach doesn’t make him the most stable option in fantasy leagues, but clearly there’s some pop here. He's worth a look in deeper formats, especially in leagues where he qualifies as a catcher.

Peter O'Brien is in the Diamondbacks starting lineup on Friday, batting fifth and playing in left field.

The Diamondbacks have said that O'Brien is up to play this time around, which makes him a very interesting fantasy commodity, especially where he may be eligible at catcher. This is a legitimate power bat, so he's worth the gamble if available on the waiver wire.

Diamondbacks recalled OF Peter O'Brien from Triple-A Reno.

O'Brien was slashing a monstrous .330/.356/.670 with 17 homers and 52 RBI over 212 at-bats with Triple-A Reno. The 25-year-old outfielder has four hits in 13 career major league plate appearances. Those in deeper NL-only formats might consider taking a flier on O'Brien given those minor league numbers, but he does not have a history of major league success at this juncture.
Fri, Jun 10, 2016 05:36:00 PM

Diamondbacks OF prospect Peter O'Brien clubbed three doubles Tuesday in a win for Triple-A Reno.

It was O'Brien's first game back after a brief promotion to the big leagues. O'Brien has been among the best hitters in the Pacific Coast League this year. He's tied for third in home runs (12), third in slugging (.618) and eighth in RBI (35). O'Brien actually slumped a little in May, hitting just .268 compared to .370 in April. The 25-year-old struck out in his only at-bat with the Diamondbacks before getting sent down.

Diamondbacks optioned OF Peter O'Brien to Triple-A Reno.

He was only with the club for a few days as an extra bench bat while the club sorted out their rotation. Fantasy owners will have to wait until there's an opening for everyday at-bats before he'll have any mixed leagues value.
Sun, May 29, 2016 08:05:00 PM

Diamondbacks recalled OF/1B Peter O'Brien from Triple-A Reno.

O'Brien has batted .306/.330/.601 with 12 homers at Reno this season. He could have some deep league value, especially in leagues where he's catcher-eligible. However, O'Brien isn't guaranteed playing time so don't go overboard.
