Nolan Arenado has the longest active hitting streak in the majors and Troy Tulowitzki isn't far behind.
Arenado and Tulowitzki look to continue their hot hitting as the Colorado Rockies attempt to win a series in an AL park for the first time in four years Wednesday against the Oakland Athletics.
Arenado is having a breakout season with career highs of 24 homers and 68 RBIs to rank among baseball's leaders in each category. The 24-year-old third baseman has also put together a 17-game hitting streak during which he's batting .364 with nine homers and 21 RBIs.
It's the longest streak by a Rockie since Arenado's franchise-record 28-game run from April 9-May 8, 2014.
Tulowitzki is batting .382 during a 14-game streak.
They each had a single in Tuesday's 2-1 victory over Oakland as Colorado (34-43) snapped its 14-game road losing streak during interleague play. The Rockies now enter this decisive finale with a chance to win their first series in an AL park since taking two of three from Cleveland from June 20-22, 2011. They've lost 11 series and split two others.
"Every win is important. Every win is gold," manager Walt Weiss said after Colorado ended its three-game skid. "Our last few games have been tough, but ... it was a big win."
Chad Bettis (4-2, 3.56 ERA) gets the ball against the A's (35-45) for the first time, but he's 0-2 with an 8.49 ERA in six career games - two starts - in interleague play.
The right-hander, though, enters this matchup having won back-to-back starts by yielding four runs in 12 1-3 innings after losing his previous two with a 7.20 ERA. Bettis gave up three runs in six innings of Friday's 8-6 win at San Francisco.
The A's are hitting .222 while dropping four of five games after winning five straight behind a .302 average.
Billy Butler, though, has a homer and a double among his four hits in this series while adding three RBIs. He's 12 for 35 (.343) in 11 career meetings with Colorado
The A's are turning to Jesse Hahn (5-6, 3.47), who should feel very comfortable with an afternoon start. The right-hander is 3-1 with a 1.53 ERA in five day games compared to 2-5 with a 4.72 ERA in 10 at night.
Hahn struggled with the lights on again Friday, surrendering five runs and nine hits - two homers - in six innings of a 5-2 loss to Kansas City. Two of the runs he allowed scored on Ike Davis' error with two outs in the third, as he botched a flip to Hahn at first.
"It was a weird night, very strange," Hahn told MLB's official website. "I do think I could have done a lot better job of getting ahead of hitters."
He gave up three runs in five innings in his only career start against Colorado on Aug. 11.
Hahn will be facing Tulowitzki for the first time, while Arenado is 1 for 4 against him.
