Cespedes out of lineup with hamstring strain
In midst of All-Star push, outfielder suffers injury running bases
DETROIT -- A's outfielder Yoenis Cespedes was out of Tuesday's lineup in Detroit and is day to day with a left hamstring strain.
Cespedes suffered the injury while racing home from first base in Monday's series-opening loss. The A's were hoping it was simply a cramp from playing in the Motor City humidity, but manager Bob Melvin confirmed the strain Tuesday.
"He's not going to do anything on the field today," said Melvin, "and then we'll see how he is on the field come tomorrow."
If Cespedes is able to play Wednesday, it will be in the designated-hitter role.
Craig Gentry made the start in left field and went 1-for-3 in Tuesday's 3-0 loss in place of Cespedes, who is riding a career-high 14-game hitting streak with a .351 average during that span.
The Cuban slugger hit .324 in 26 games in June after batting just .245 over his first 52 games. Those numbers, combined with a spike in outfield assists -- most of them highlight-worthy -- have led to a large boost in All-Star support.
Cespedes currently ranks third among all American League outfielders.

Norris takes batting practice, nearing return
DETROIT -- Derek Norris was not in the A's lineup for a fourth straight game Tuesday, but the A's catcher had at least improved to the point where he was considered potentially available off the bench.
Barring any setbacks, Norris will be back behind the plate Wednesday.
On Tuesday, Norris took batting practice on the field for the first time since Friday, when lower back soreness forced him out of a game in Miami. He also caught lefty Tommy Milone's bullpen session Tuesday afternoon.
Stephen Vogt caught southpaw Brad Mills on Tuesday, while John Jaso served as designated hitter.
• Left-hander Scott Kazmir left Monday's start with a cramp in his left calf but remains on track to make his next start against the Blue Jays on Saturday.
• Southpaw Drew Pomeranz (fractured right hand) threw a bullpen session on Tuesday for the first time since hitting the disabled list. He did so without a glove on his hand, which hasn't healed enough for him to catch the ball yet.
