West Notes: Scutaro, Singleton, Martinez

Due to his back injury, Marco Scutaro still isn't playing in extended spring training games, but it's unlikely the Giants will make a trade to replace him anytime soon, Henry Schulman of the San Francisco Chronicle writes. This week's Ike Davis trade aside, deals involving valuable players generally aren't made in April, and the Giants would likely have to pay heavily to acquire a talented infielder. Later this summer, the Giants still might not make second base their top priority, Schulman suggests — they may instead focus on their bench. Here are more notes from the West divisions.

• The Astros are excited about first baseman Jonathan Singleton's performance at Triple-A Oklahoma City, writes MLB.com's Brian McTaggart. The Astros recently promoted top prospect George Springer, and Singleton, who is hitting .343/.449/.776 so far, might not be far behind. "When we sent him down at Spring Training, we told him he was going to let us know when he was ready to come up here by his performance, and so far he's doing an outstanding job," says assistant GM David Stearns. "We'd like to give him more time to continue to work on the aspects of his game that we identified with him that needed some improvement. So far he's addressing them."
• Former Astros outfielder J.D. Martinez is making a strong case to make it back to the big leagues with the Tigers, MLive.com's James Schmehl writes. Martinez is hitting .308/.366/.846 with a remarkable ten home runs in 71 plate appearances for Triple-A Toledo, and the Tigers are currently playing with only three bench players. The Astros somewhat surprisingly released Martinez last month, even though he wasn't on their 40-man roster at the time and was a 26-year-old with 975 plate appearances of big-league experience. Martinez's salary at Triple-A was apparently a factor in the Astros not being able to find another organization for him.
