Edgar Olmos SP SEA 1 Day

Olmos was claimed off waivers by the Mariners on Thursday.

Olmos spent last season in the Marlins system, seeing time at both Double-A Jacksonville and Triple-A New Orleans. In 51.1 Triple-A innings, Olmos posted a 3.86 ERA, registering 44 strikeouts and 17 walks.

Charles Brewer SP ARI 1 Day

Brewer was designated for assignment Thursday, Nick Piecoro of AZ Central Sports reports.

Brewer began last season at Triple-A Reno but struggled to a 4.99 ERA over 126.1 innings. He was demoted to Double-A Mobile, where he turned things around to post a 2.91 ERA and 1.154 WHIP with 42 strikeouts and 14 walks.

Mike Bolsinger SP ARI 1 Day

Bolsinger was designated for assignment Thursday, Nick Piecoro of AZ Central Sports reports.

Bolsinger spent the majority of the season at Triple-A Reno, where he posted a 3.93 ERA and 1.353 WHP across 91.2 cumulative innings. He made 10 appearances, including nine starts, for the Diamondbacks, struggling to a 1-6 record with a 5.50 ERA.

Zach Lee SP LAD 1 Day

The Dodgers added Lee to their 40-man roster Thursday, Bill Shaikin of the LA Times reports.

Lee had a rocky 2014 campaign, but he entered the year as one of the Dodgers' top prospects, so the team was unwilling to expose him to the Rule 5 draft. Lee figures to get another crack at the Triple-A level next season.

Pedro Florimon SS PIT 1 Day

The Pirates claimed Florimon off waivers from the Nationals on Thursday, James Wagner of the Washington Post reports.

Florimon did not appear in a game with the Nationals after being claimed by the club in mid-September. He struggled mightily with the bat last season but could get a shot to compete for a utility job during spring training.

Ryan Mattheus RP WAS 1 Day

The Nationals outrighted Mattheus off their 40-man roster Thursday, James Wagner of the Washington Post reports.

Mattheus, with 145 big league games under his belt, elected to become a free agent rather than accept his Triple-A assignment. He appeared in just seven big league games last season, but his experience should help him land a job elsewhere.

Ezequiel Carrera CF DET 1 Day

Carrera was designated for assignment by the Tigers on Thursday.

Carrera appeared in 45 games with the Tigers last season, but last week's trade for Anthony Gose made him expendable. He could garner some interest on the waiver wire thanks to his ability to man center field.

David Martinez RP TEX 1 Day

Martinez signed a minor league contract with an invite to training camp with the Rangers, ESPN.com reports.

Martinez made three appearances in the majors with the Astros, but saw most of his playing time with Triple-A Oklahoma City, where he posted a 5.64 ERA in 22 games. He will try to make the Rangers' roster as a depth pitcher in the bullpen.

Chris Gimenez C/1B TEX 1 Day

Gimenez has agreed to a contract with the Rangers, ESPN.com reports.

Gimenez spent most of last season in triple-A, but did play 42 games with the Rangers and Indians. In those major league games, Gimenez hit .241 with 11 RBI. He will try to make the Rangers' roster again, like he did last season.

Zelous Wheeler 3B NYY 1 Day

The Yankees sold Wheeler's rights to Tohoku of Japan's Pacific League on Thursday.

Wheeler posted an impressive .834 OPS with Triple-A Scranton/Wilkes-Barre last season, but he also posted an unsightly .528 OPS at the big-league level, so the Yankees decided to move on and give him a chance to play overseas next season.
