Roto Roundup: Jair Jurrjens to the DL, Victor Martinez Injured

Braves starter Jair Jurrjens was placed on the DL on Saturday with a right knee strain. Jurrjens had surgery on the same knee in the offseason, The Braves called up AAA starter Mike Minor to start today in Jurrjens spot.

Tigers catcher/DH was pulled from last night's game with an apparent knee injury which he suffered from a collision at home plate. He could not put weight on his knee when leaving the field. He was diagnosed with a sprained knee, but we don't know if he will require a DL stint as of now.

Rangers third baseman Adrian Beltre re-injured his hamstring testing it while running the bases yesterday and will be out another 3 weeks. Tough break for the Rangers.

The Phillies activated starter Roy Oswalt last night and he will start today vs the Giants in San Francisco. I would wait on activating him, as he is returning from a back injury.

More Roundup after the jump:

Reds outfielder Yonder Alonso hit his first major league home run yesterday off of Cubs starter Carlos Zambrano and went 2-2 with 2 RBIs and a walk. He has hit well since his callup, and should see more playing time going forward with the Reds falling further out of the wildcard race.

Cubs shortstop Starlin Castro went 2-5 with 2 runs and 4 RBIs yesterday afternoon, and is now hitting .313-.34-.431 with 4 HRs, 51 RBIs and 12 SBs. He has a great bat, but I wonder when we will see double digit power from him.

Red Sox outfielder Jacoby Ellsbury may be moving ahead of teammate Adrian Gonzalez in the AL MVP race as he went 2-4 with a HR and 6 RBIs yesterday as the Red Sox beat  CC Sabathia and the Yankees. Ellsbury is hitting .321-.377-.522 with 19 HRs, 72 RBIs, 84 runs and 31 SBs.

Ellbury's teammate Carl Crawford went 4-4 with 3 runs, an RBI and a SB yesterday. I ranked Crawford as my #1 fantasy outfielder at the beginning of the season, but he has underperformed my expectations in a huge way. Heading into 2012, he should fall in most drafts, unless he turns things up a few notches the rest of the way.

Phillies starter Cole Hamels held the Giants to one run in a complete game 7 hitter yesterday to win his 13th game of the season. He lowered his ERA to 2.53 and WHIP to 0.96, and a 150-31 K/BB rate in 167 innings thus far. Hamels will get plenty of votes for NL Cy Young this year.

Brewers first baseman Prince Fielder went 3-3 with a HR, 2 runs, 2 walks, and 4 RBIs last night, and is hitting .300-.416-.562 with 25 HRs and 83 RBIs thus far. In his last 10 games, he is 15-35 with 3 HRs and 9 RBIs. Just read a tweet where ESPN's Buster Olney predicts the Fielder will sign with the Cubs.

Astros second base prospect Jose Altuve went 1-3 with a walk and a run scored last night, and is hitting .316-.344-.368 with 3 RBIs and 3 extra base hits in his first 57 at bats in the big leagues. The Astros are going young, so he will get plenty of starts going forward.

Athletics outfielder Coco Crisp went 2-5 with 2 runs scored and 4 SBs last night. Crisp is hitting .275-.330-.394 with 5 HRs, 36 RBIs, 58 runs and 37 SBs in 46 attempts. He was removed from the game with a strained calf and will probably sit out Sunday's game.

Athletics starter Brandon McCarthy shutout the Rays for 8 innings last night on 5 hits, no walks and 5 strikeouts. McCarthy is 5-5 with an excellent 3.31 ERA, 1.17 WHIP and a 74-16 K/BB rate in 108.2 innings pitched.

The Padres scored 15 runs on Friday night and 13 runs last night, but the bigger story for me was the performance of starter Corey Luebke. He held the Pirates to one run on 5 hits, no walks and 9 strikeouts. He is now 4-6 with a 3.06 ERA, 0.96 WHIP and a 91-22 K/BB rate in 88.1 innings. The Padres pitching staff will be solid in a few years with Mat Latos, Luebke,  Casey Kelly and possibly Simon Castro. Luebke has given up 2 runs or less in 6 of his last 8 starts.

Dodgers pitching prospect Nathan Eovaldi held the Diamondbacks to 2 runs to win his first major league start. He gave up 4 hits, walked 2 and struck out 7 in 5 innings. Eovaldi was a non-prospect coming into the 2011 season and has dominated AA this season, earning a call up. I think he could be in the Dodgers rotation in 2012. I wrote a piece on Eovaldi over at Minor League Ball that is scheduled to post at 8am today.

Indians second base prospect Jason Kipnis went 2-5 with a HR and 2 RBIs last night and is now hitting .255-.327-.617 with 5 HRs, 8 RBIs, 8 runs and 7 extra base hits in his first 47 at bats in the big leagues.
