OAKLAND -- Bartolo Colon becomes eligible to pitch in the Major Leagues again April 6, when the Athletics are in Houston for an American League series with the Astros.
Right-hander Dan Straily is penciled in to start the series opener in Houston on Friday. So, what happens the next day?
Colon does not currently count against the A's 40-man roster, but a move will be needed if he pitches against the Astros.
"I could fit him in the sixth day and let everybody else get an extra day," A's manager Bob Melvin said. "I'm not sure yet. He could get a couple of innings [in the Minors] if he needs it."
Straily could be pitching to keep his spot in the rotation and Melvin said his last exhibition start, Saturday vs. the Giants, may help decide the process.
"The last game before the first start you want to ramp it up," Melvin said before Saturday's game. "There's a difference today from regular Spring Training. Arizona can be a tough place to pitch. This is more like a regular-season game."
Melvin mentioned the stadium size and intensity levels as important indicators.
"You want to leave a good impression going into your next start," Melvin said.
A's put Nakajima on DL to finalize roster
OAKLAND -- Shortstop Hiro Nakajima will start the season on the disabled list as the Oakland Athletics announced their final moves of the spring following Saturday's 4-3 win over the San Francisco Giants.
The A's also optioned left-hander Pedro Figueroa and infielder Andy Parrino to Triple-A Sacramento and reassigned right-hander Mike Ekstrom, left-hander Hideki Okajima and catcher Luke Montz to their Minor League camp.
Oakland opens the season Monday night against the visiting Seattle Mariners with 12 pitchers and first baseman Nate Freiman, a Rule 5 Draft pick.
Bartolo Colon remains on the suspended list.
"Personally it feels like I could come back earlier," Nakajima said after learning of the decision to put him on the 15-day disabled list. "It is still early and I waas told it has to be a gradual process, so I'm going to stick to their schedule."
Nakajima injured his left hamstring in the 10th inning of Tuesday's game against the Cleveland Indians in Arizona.
He had just ended an 0-for-22 streak with a single and hurt his hamstring trying to reach second on an ensuing bunt.
"I came to camp early and I think I might have gotten a little tired," Nakajima said. "I will take this opportunity to rest up, do my rehab work, and come back healthy."
Fighter Cormier tosses first pitch before A's game
OAKLAND -- UFC heavyweight title contender Daniel Cormier donned an A's jersey and threw out the first pitch before Saturday's final exhibition game of the season.
Cormier (11-0) works out at the American Kickboxing Academy in San Jose, where he has lived since 2010. He'll be fighting former UFC champion Frank Mir on April 20 in San Jose.
"I grew up in Louisiana so there it was either the Astros or Braves," Cormier said. "Being in San Jose, I'm more in tune with Oakland and San Francisco. I love the Bay Area."
The two-time Olympic wrestler was a little out of the strike zone but threw it well enough for Jerry Blevins to easily catch.
