There’s a reason bullpens lead to night sweats for most managers and front-office types.

So much rides on what happens in the innings after the starter has been yanked. Finding the right mental and physical mettle in relievers can be as harrowing as attempting to survive a high school chemistry experiment while blindfolded.

Entering this season, Rays manager Kevin Cash and baseball overlord Matt Silverman have much to learn about their bullpen, which stands as sort of a reconstruction project. Jake McGee is gone. Brandon Gomes, too.

The Rays will rely on Brad Boxberger to throw gas in the ninth inning, but building the bridge to him will take tinkering through the spring and beyond.

Tampa Bay was in need of a veteran arm to plug-and-play in those late frames. They hope they found an answer with right-hander Ryan Webb.

The 30-year-old Webb, a Clearwater native, has bounced between the Padres, Marlins, Orioles and Indians since 2009. He’s 17-18 for his career with a 3.35 ERA and 260 strikeouts. He threw a career-high 80 1/3 innings with Miami in 2013, but he threw just 50 2/3 last year with Cleveland.

Webb will prove to be a savvy pickup if he becomes a reliable heavy-lifter. The Rays are high on his experience, which includes 376 innings pitched in 357 major-league appearances.

He’s also a ground-ball pitcher, which made him catch Silverman’s eye.

Like all relievers, there’s mystery involved with Webb. Cash and Silverman hope he becomes a no-sweat solution to their bullpen puzzle.
