OAKLAND -- A's manager Bob Melvin could probably talk about Marcus Semien forever and still not run out of superlatives.
Oakland's shortstop is one of the hardest workers in all of baseball, as evidenced by his massive improvement defensively over the past few years. This season, Semien has taken his offensive production to another level as well.
The 28-year-old is slashing .280/.365/.443 with 10 home runs, 36 RBI, and 48 runs scored. He's on pace to set career-highs in nearly every major offensive category, including hits, walks, runs, and RBI.
"He's just become a complete player," Melvin praised. "Offensively, defensively, he's got leadership qualities, he's out there every day. There are a lot of things to like about Marcus Semien. He continues to get better and I don't see that slowing down either. He's very aware of what he needs to work on and what it takes to get better.
"Nobody works harder."
It probably seems crazy now, but Oakland actually entered the season without a set leadoff hitter. That changed in a hurry, as Semien grabbed the role and didn't let go.
"I just want to get on base," he said. "That's what I've been trying to do more of this year and just stay in the strike zone. ... I've been walking more too. I'm just trying to get on base for the middle of the order."
Semien has certainly done that. He is currently riding a career-high 14-game hitting streak, batting .390 with three home runs, four doubles, and 11 RBI during that stretch.
"Better direction, better timing with the fastball and then being able to take the pitches out of the zone, those offspeed pitches," Semien explained. "You get in better counts, and when you're catching up to the fastball and hitting in good counts, good things will happen."
Semien's .365 on-base percentage ranks fifth among major league shortstops. Prior to this season, he had never posted an on-base percentage higher than .325.
"I used to lead him off against lefties and not righties," Melvin said. "Now we're comfortable leading him off (against either). ... He sets the table for a lot of guys. You see the RBI through the lineup. A lot of it has to do with him being on base quite a bit."

Semien has also reduced his strikeout rate from a year ago, punching out just 47 times in 296 at-bats (15.9 percent). Last season, he struck out 131 times in 632 at-bats (20.7 percent).
"I can't say enough about what he means to this team," Melvin said. "He hits the ball the other way. If you shift on him, he'll shoot the ball in the hole. He's just very aware of what's going on out there and he shows up on both ends."
