The Mariners have traded 30-year old lefty swinging 1B/3B Jack Hannahan to the Red Sox for either a player to be named later or cash. Hannahan played in 63 games in AAA-ball for the Mariners this year and he was 51 of 224 (.228 avg, .675 OPS) with 32 runs scored, 5 homers and 33 RBIs. Hannahan has not played in the big leagues yet this season. He played in 51 games for the Mariners last season and he was 34 of 148 (.230 avg, .656 OPS) with 15 runs scored, 3 homers, 11 RBIs and 1 stolen base. The Mariners won’t miss Hannahan at all as they are the likely winners in this trade.

24-year old lefty swinging 3B Matt Mangini didn’t come into this season as one of the Mariners’ top 30 prospects but he’s playing like one in AAA. Mangini has played in 73 games in AAA-ball so far this season and he is 76 of 245 (.310 avg, .901 OPS) with 43 runs scored, 10 homers, 41 RBIs and 2 stolen bases. If the Mariners either trade Jose Lopez or he gets hurt look for the Mariners to give Mangini his first shot at the majors. If neither of those things happen the Mariners could call up Mangini when rosters expand in September provided that he keeps playing well in the minors.

The Mariners have signed 35-year old righty reliever Jamey Wright and he will be in the pen starting tonight. Wright pitched in 18 games (0 starts) earlier this season for the Indians and he was 1-2 with a 5.48 ERA and a 1.59 WHIP. He has now pitched in 438 games (246 starts) in his major league career and he is 83-117 with a 5.03 ERA and a 1.58 WHIP. To make room on the active roster the Mariners demoted Chad Cordero who refused the assignment and has become a free agent. Cordero pitched in 9 games (0 starts) for the Mariners this season and he was 0-1 with a 6.52 ERA and a 1.55 WHIP.

Many “experts” picked the Mariners as their darkhorse in the A.L. West. They were very wrong! The Mariners finished up the first half of the season with a 35-53 record which has them in last place in the A.L. West, 15 games behind the Rangers. It has not all been bad for the Mariners so here’s a lot at the surprises and disappointments for the Mariners in the first half of the year:

Pleasant Surprises: The Mariners didn’t expect much out of 27-year old lefty starting pitcher Jason Vargas but he has been outstanding so far this year. Vargas has started 17 games for the Mariners this year and he is 6-4 with a 3.09 ERA and a 1.19 WHIP. 26-year old righty starting pitcher Doug Fister looked decent at the end of 2009. He has been very solid in 2010 for the Mariners. Fister has started 13 games for the Mariners so far this season and he is 3-4 with a 3.09 ERA and a 1.07 WHIP. 29-year old SS Josh Wilson started the season in the minors but he took over as the starter at SS when Jack Wilson got injured. Josh Wilson has played in 56 games for the Mariners this year and he is 50 of 189 (.265 avg, .663 OPS) with 14 runs scored, 1 homer, 14 RBIs and 3 stolen bases. 36-year old DH Mike Sweeney has been solid for the Mariners, when healthy. He has played in 30 games for the Mariners this season and he is 26 of 99 (.263 avg, .802 OPS) with 11 runs scored, 6 homers, 18 RBIs and 2 stolen bases.

Disappointments: The Mariners sure have a lot of guys who fit this description but I will only list the Top Five. 32-year old switch hitting 2B Chone Figgins was supposed to give the Mariners an awesome 1-2 punch at the top of the order with Ichiro…but that hasn’t happened yet. Figgins has played in 87 games for the Mariners this year and he is 75 of 319 (.235 avg, .608 OPS) with 38 runs scored, 0 homers, 22 RBIs and 24 stolen bases. 27-year old lefty swinging Casey Kotchman has been so bad at first base that the Mariners traded for two guys to replace him in Russell Branyan and Justin Smoak. Kotchman has played in 69 games for the Mariners this year and he is 47 of 216 (.218 avg, .670 OPS) with 20 runs scored, 7 homers and 29 RBIs. Ken Griffey Jr. was so awful ths season for the Mariners that he decided to retire so he could catch up on his sleep. Griffey played in 33 games in his last year with the Mariners and he was 18 of 98 (.184 avg, .454 OPS) with 6 runs scored, 0 homers and 7 RBIs. 32-year old switch hitting OF Milton Bradley was supposed to really help the offense in 2010 but it hasn’t turned out that way. Bradley has played in 62 games for the Mariners this year and he is 44 of 210 (.210 avg, .661 OPS) with 24 runs scored, 8 homers, 28 RBIs and 6 stolen bases. 28-year old righty reliever David Aardsma had a breakout 2009 as the Mariners’ closer. But he has been awful this year for the Mariners. Aardsma has pitched in 31 games (0 starts) for the Mariners this year and he was 0-6 with 16 saves, a 5.40 ERA and a 1.34 WHIP.

The Mariners have released 33-year old righty reliever Mike Koplove. Koplove pitched in 22 games in AAA-ball this season and he was 0-1 with 1 save, a 4.45 ERA and a 1.66 WHIP. The Mariners decided to let Koplove loose as they are going to try to rebuild with youth. This also gives Koplove a chance to sign with a new team.
