The Giants have placed 28-year old switch hitting IF/OF Eugenio Velez on the 15-day disabled list with a concussion. He was hit in the head the other day while on the bench by a line drive off the bat of Pat Burrell. Velez has played in 21 games for the Giants this year and he is 9 of 46 (.196 avg, .644 OPS) with 7 runs scored, 2 homers and 8 RBIs. The Giants have called up 26-year old righty swinging infielder Ryan Rohlinger to replace Velez on the active roster. Rohlinger has played in 10 games for the Giants this year and he is 3 of 14 (.214 avg, .527 OPS) with 1 run scored and 1 RBI.

The Giants have placed 31-year old lefty reliever Jeremy Affeldt on the 15-day disabled list with a slight tear of his left oblique muscle. Affeldt has pitched in 37 games (0 starts) for the Giants this year and he is 2-3 with 3 saves, a 4.11 ERA and a 1.66 WHIP. The Giants don’t have a lefty reliever in the pen now with Affeldt and Runzler on the D.L. The Giants have recalled 27-year old righty reliever/starter Joe Martinez to replace Affeldt in the bullpen. Martinez has pitched in 3 games (1 start) for the Giants this year and he is 0-1 with a 4.00 ERA and a 1.89 WHIP.

The Giants have placed 25-year old lefty reliever Dan Runzler on the 15-day disabled list with a dislocated left kneecap. Runzler has pitched in 36 games (0 starts) for the Giants this season and he is 3-0 with a 3.30 ERA and a 1.53 WHIP. The Giants have recalled 27-year old righty reliever/starter Joe Martinez to replace Runzler in the pen. Martinez has pitched in 2 games (1 start) for the Giants earlier this year and he was 0-1 with a 4.91 ERA and a 1.64 WHIP. The Giants are going to miss Runzler who was pitching pretty well this year.

35-year old righty swinging LF Mark DeRosa will have season ending wrist surgery next week. DeRosa played in 26 games for the Giants this year and he was 18 of 93 (.194 avg, .537 OPS) with 9 runs scored, 1 homer and 10 RBIs. The Giants were lucky to find Pat Burrell on the free agent market as he is giving the Giants the bat they thought they were going to have in DeRosa. Burrell has played in 15 games for the Giants so far this season and he is 15 of 44 (.341 avg, 1.014 OPS) with 6 runs scored, 3 homers and 8 RBIs. The Giants hope Burrell keeps up the good work and that DeRosa returns healthy in 2011.

The Giants have placed 31-year old righty starting pitcher Todd Wellemeyer on the 15-day disabled list with a right quad strain. Wellemeyer has pitched in 12 games (11 starts) for the Giants this year and he is 3-5 with a 5.52 ERA and a 1.50 WHIP. He has given up a stunning 12 homers while walking 35 batters in only 58 2/3 innings pitched this year. The Giants have called up 27-year old righty starting pitcher Joe Martinez to replace Wellemeyer on the pitching staff. Martinez has started 11 games in AAA-ball this year and he is 5-2 with a 3.07 ERA and a 1.26 WHIP. He got his first taste of the majors last year for the Giants working in 9 games (5 starts) in which he is 3-2 with a 7.50 ERA and a 1.93 WHIP. I would have to think that Martinez’ stay might only be until Wellemeyer’s spot comes up in the rotation with Madison Bumgarner getting a call.
