Jake Buchanan RP HOU 6 Mins

Buchanan was optioned to Astros' minor league camp on Sunday.

Buchanan, who allowed seven runs (five earned) on 12 hits and three walks with four strikeouts over 8.1 Grapefruit League innings, was beaten out by Samuel Deduno to be the Astros' long man out of the bullpen to open 2015. The 25-year-old will likely stretch out as a starter with Triple-A Fresno.

Vic Black RP NYM 11 Mins

Black (shoulder) threw a bullpen Monday and hopes to pitch in a game Wednesday, The Record's Matt Ehalt reports.

Black may still need to start the year in the minor leagues as he has been limited this spring by the shoulder injury. When he's fully healthy and has some innings under his belt, he will join the Mets' bullpen.

Matt Dominguez 3B HOU 11 Mins

Dominguez was optioned to Astros' minor league camp on Sunday.

In 16 Grapefruit League games, Dominguez hit .250 with two RBI and no extra-base hits over 36 at-bats. The 25-year-old will open 2015 with Triple-A Fresno, where he'll get regular at-bats while playing third and first base.

Carlos Villanueva P STL 15 Mins

Villanueva has been told that he will make the 25-man roster out of camp, MLB.com's Jenifer Langosch reports.

While Villanueva's career as a starter fizzled out, he has complied a 3.55 ERA and 439 strikeouts in 439 career innings as a reliever. He should slot in as the Cardinals' long reliever, pitching mostly in low-leverage situations.

Xavier Avery CF DET 20 Mins

Avery has been assigned to minor league camp by the Tigers.

He was signed as a depth option on a minor league deal, but with a slew of healthy options available, Avery was deemed expendable. If he remains in the organization, Avery will head to Triple-A Toledo to begin the season.

Carlos Martinez P STL 21 Mins

Martinez appears to be the favorite to win the fifth starter spot for the Cardinals, the St. Louis Post Dispatch's Derrick Goold reports.

Jaime Garcia had a setback with his surgically-repaired shoulder and will be shut down, eliminating him from the competition. Martinez is in line to start Wednesday, and while the Cardinals have not announced who the fifth starter will be, they did announce that they will only take five starters with them to start the season. Given the way the schedules line up, it appears Marco Gonzales is ticketed for Triple-A. While Martinez has more upside than Gonzales, the former has also had major issues pitching deep into games, as he is often inefficient with his pitches. Whoever is in that role is worth a flier in most formats, but expectations should be tempered.

Edwin Encarnacion 1B/DH TOR 21 Mins

Encarnacion (back) returned to the lineup on Thursday and looks as if he'll be ready to play on Opening Day, Shi Davidi of Sportsnet.ca reports.

Encarnacion's back could be a big issue that plagues both him and the Blue Jays lineup throughout the year. Originally scheduled to play first base full-time, a balky back could force him into playing designated hitter more often. With Justin Smoak's improvement at the plate this season, coupled with his strong defensive skills, it could move Encarnacion to DH, leaving Dioneer Navarro as the potential odd man out. With first base eligibility no matter what, Encarnacion should still be a good source of power as he attempts to play more than 150 games for the second time in his career.

Aaron Westlake 1B DET 22 Mins

Westlake has been assigned to minor league camp.

He'll likely return to Double-A Erie after hitting .236/.293/.396 there last season. Westlake had a chance to hang around on the Opening Day roster if both Miguel Cabrera and Victor Martinez were unavailable to begin the season, but both players are on track to be in the Opening Day lineup.

Jordan Lennerton 1B DET 23 Mins

Lennerton has been assigned to minor league camp.

The Tigers appear likely to have Miguel Cabrera and Victor Martinez healthy for Opening Day, rendering Lennerton and Aaron Westlake expendable. Lennerton may end up at Triple-A Toledo if he sticks in the organization.

Preston Claiborne RP MIA 25 Mins

Claiborne has been optioned to Triple-A, Joe Frisaro of MLB.com reports.

He'll likely yo-yo between Triple-A and Miami this season as one of the team's fringe reliever with the flexibility of minor league options.
