Alexander is expected to work in bulk relief behind opening pitcher Cole Sulser in Monday's game against the Phillies, Marc Topkin of the Tampa Bay Times reports.
Alexander is taking over the rotation spot vacated by lefty Jeffrey Springs (elbow), who landed on the injured list Sunday. Over his 19 appearances (seven starts) with Tampa Bay this season, Alexander sports a 6-4 record with a 5.66 ERA, 1.35 WHIP and 75:21 K:BB across 89 innings. He's been especially vulnerable to the long ball, giving up a career-high 22 home runs.
