Blue Jays prospect Sean Nolin is expected to start Friday against the Orioles.
A sixth-round pick in 2010, Nolin has a 1.17 ERA while striking out a batter per inning this year at Double-A New Hampshire. Chad Jenkins had also been a candidate to start, but will likely be sent down in a corresponding move. Nolin has made just six starts above A-ball and isn't recommended streaming option in fantasy leagues.
Athletics activated SS Hiroyuki Nakajima from the 15-day disabled list; optioned him to Triple-A Sacramento.
Nakajima is still working his way back from a hamstring injury he suffered late in spring training. His 20-day rehab window expired on Wednesday, so the Athletics are keeping him in the minors.
Mariners purchased the contract of C Jesus Sucre from Triple-A Tacoma.
Sucre, 25, has a .302/.371/.321 batting line in 14 games as a part-time catcher at the Triple-A level. Mike Zunino still needs development time, so the Mariners are promoting Sucre to replace the struggling Jesus Montero on their active roster.
Mariners optioned C Jesus Montero to Triple-A Tacoma.
Montero has been a major disappointment this season, batting just .208/.264/.327 with three home runs and nine RBI in 29 games. The Tacoma News Tribune says Montero is "no longer viewed as a catcher at the big league level" and is expected play first base and DH in the minors. The Mariners have promoted Jesus Sucre to replace him on the active roster.
Royals prospect Yordano Ventura allowed seven runs (six earned runs) on nine hits over 4 1/3 innings in his start Wednesday with Double-A Northwest Arkansas.
Ventura hadn't allowed more than two earned runs in any of his previous eight starts, so it's the first time he's struggled this season. The 21-year-old top prospect has a 2.82 ERA with a 1.12 WHIP and 12.1 K/9 over 45 innings at the Double-A level. Prior to Wednesday's outing, he had a a pair of 10-strikeout games and 32 total strikeouts in his last four starts.
Orioles prospect outfielder Henry Urrutia is batting .333/.413/.542 with three home runs and 19 RBI in 25 games with Double-A Bowie.
Urrutia, 26, defected from Cuba last season but visa issues delayed him from making his debut until a month ago. Given his advanced age and track record, he likely isn't far off from a promotion to Triple-A Norfolk.
Orioles prospect Brandon Kline (ankle) has been placed on the disabled list with Low-A Delmarva.
Kline underwent surgery Thursday to repair a non-displaced ankle fracture and will be sidelined 6-8 weeks. A second-round pick in 2012, Kline had a 5.86 ERA in seven starts at the Orioles' Low-A affiliate.
Padres optioned RHP Burch Smith to Triple-A Tucson.
Smith was sent down after he lasted just one-plus inning in a loss Wednesday to the Cardinals. The 23-year-old struggled with an 18.41 ERA in his first three major league starts. Smith opened the season with Double-A San Antonio, but the Padres are hoping he can turn things around the Triple-A level.
