Lowe strained a hamstring during warmups before a late-season game in Oakland and was unavailable for the ALDS and ALCS. He would be a valuable right-handed addition to the bullpen for possible middle relief or as a power arm in late-game situational matchups.
He could potentially replace struggling right-hander Koji Uehara in the next round.
"I'll be ready," Lowe said during a brief open clubhouse session Wednesday prior to Game 4 as rain washed out batting practice for the Rangers and Detroit Tigers.
Uehara has experienced a disappointing postseason with a bloated ERA of 13.50. He made his ALCS debut in Game 3 and immediately gave up an RBI single in the sixth inning and then a seventh-inning lead-off home run to Miguel Cabrera in the 5-1 loss. Afterward, Uehara said he believes manager Ron Washington has lost confidence in him.
On Wednesday, Washington said if needs to go to Uehara again he will.
Lowe said he completed a second bullpen session on Tuesday. He threw 55 total pitches in the two sessions and said the next step is to face live hitters, although he said a session has not been planned. He said if the ALCS is extended beyond five games the team might opt to send him to Arizona to work out and prepare for a potential second trip to the World Series.
Lowe was injured last season when the Rangers traded for him as part of the Cliff Lee deal. He missed the ALDS and ALCS, but was activated for the World Series and did not pitch well.
He was throwing quite well late this season. In his final seven appearances, Lowe, who last pitched on Sept. 20 at Oakland, allowed two runs on two hits in 5 1/3 innings. He finished he season with a 3.80 ERA and 42 strikeouts in 45.0 innings.
Darren O'Day is another right-hander that could be added if the Rangers advance. Slender right-hander Yoshinori Tateyama did not make the ALDS roster, but is on the ALCS roster after Washington opted for an additional pitcher on the 25-man roster.
