April showers bring May flowers. What do May flowers bring?
Well, for the San Francisco Giants, significant injuries. At least that’s been true over the past few seasons.
Mark DeRosa, Buster Posey, Pablo Sandoval, Ryan Vogelsong, Angel Pagan. All suffered significant injuries that cost them weeks of playing time in May.
Wednesday’s injury may have been the most frustrating.
In the top of the ninth, after he had just escaped a bases-loaded jam with the help of a double play ball, Santiago Casilla came to the plate for the first time since 2012.
Manager Bruce Bochy said afterwards that he gave Casilla instructions not to swing. But Casilla went up there hacking, working the count full before hitting a chopper up the middle. Rockies shortstop Troy Tulowitzki charged the ball and threw to first. Casilla raced down the baseline with his hair on fire, as if they play were in Game 7 of the World Series.
It was a game in May, and the Giants were leading 5-1. Just before he reached the bag, Casilla pulled up, then fell over the bag and began writhing in pain. Casilla suffered a hamstring injury so bad that he could not put wait on the leg and had to be helped off the field by two trainers.
And this came after starter Matt Cain left the game early when he felt his hamstring tighten up.
Casilla is definitely going on the DL. For how long, we won’t know until an MRI is performed Thursday. But it didn’t look good. By the looks of things, if the Giants get Casilla back before the All-Star break, they would be lucky.
But it seems to follow a disturbing trend of key injuries suffered by Giants in the month of May.
Here’s a look back at others since 2010:
Mark DeRosa: Prior to the 2010 season, Mark DeRosa signed a two-year, $12 million deal to be a veteran presence in the lineup. But in May of 2010, DeRosa went on the DL with a wrist injury that ended his 2010 season after playing 26 games in 2010. He came back to play 47 games in 2011, mostly as a reserve. He also started a DL stint in May 2011.
Edgar Renteria: Renteria went on the DL twice in May 2010, the first on May 7 with a strained groin. He returned May 22, played three games then went back on the DL with a strained hamstring for about a month. He would return, suffer other injuries, but return in the postseason to deliver one of the biggest hits in Giants history in Game 5 of the World Series.
Buster Posey: The biggest May injury was Posey’s season-injury ankle injury on May 26 when he got plowed by Scott Cousins.
Jeremy Affeldt: Affeldt went on the DL May 2 with a sprained knee sustained when his 4-year-old son lept into his arms after Affeldt returned home after a game. Now, granted, the injury occurred in late April, but Affeldt went on the DL in May. Affeldt missed the minimum, so it wasn’t major injury, but worth mentioning.
Pablo Sandoval: Almost a year after breaking the hamate bone in his right hand, Sandoval breaks the hamate bone in his left hand, leaving a game early against the Marlins on May 2. He would be out until June 9.
Santiago Casilla: This isn’t the first time Casilla visited the DL in May. Last season, he went on DL on May 21 with a cyst in his right knee and did not return from the DL until July 14.
Ryan Vogelsong: Vogelsong was off to a bad start in 2013. But he looked to be turning things around with his best start of the season, throwing five shutout innings against the Nationals. Then he broke his hand swinging at a pitch at the plate. He would be out until Aug. 9.
Angel Pagan: Pagan supplied perhaps the most exciting play of the 2013 season for the Giants when he won a game against the Rockies with a 10th-inning, inside-the-park home run. But Pagan hurt his hamstring on the play on May 25. They waited until June 7 to put him on the DL. He tried to return later in June, but aggravated the injury on June 20 playing for Class San Jose. He would later have surgery and be out until Aug. 30.
Brandon Belt: Belt went on the DL after suffering a broken thumb when he was hit by a pitch from the Dodgers’ Paul Maholm on May 9. He’s not expected back until late June, at the earliest.
