Rondon opted to retire from professional baseball Tuesday, Chris Cotillo of The Springfield Republican reports.

EDGE Analysis

The 33-year-old spent spring training with the Phillies before being released and subsequently signing a minors deal with the Red Sox, but he's now decided to hang up his cleats. Rondon appeared in 444 games between the Cubs, Astros and Diamondbacks over his eight-year big-league career, and he finished with a 3.49 ERA and 1.20 WHIP while recording 92 saves over 436 innings.

Rondon signed a minor-league contract with the Red Sox on Tuesday, Chris Cotillo of The Springfield Republican reports.

EDGE Analysis

The 33-year-old with in camp with the Phillies as a non-roster invitee, but he was released by the club last week. Rondon had a 7.65 ERA, 1.80 WHIP and 23:11 K:BB over 20 innings with the Diamondbacks last season, and he should head to Triple-A or the alternate training site for the Red Sox.

Rondon was released by the Phillies on Thursday, Matt Breen of The Philadelphia Inquirer reports.

EDGE Analysis

Rondon was brought in as a non-roster invitee prior to camp with an eye on bolstering a bullpen that was historically poor last season, but the Phillies evidently saw enough from their numerous other additions that they didn't plan on giving him a roster spot. His 7.71 ERA in seven spring innings likely didn't help his case, though his 8:2 K:BB was solid.

Rondon signed a minor-league contract which includes an invitation to big-league camp with the Phillies on Tuesday, Scott Lauber of The Philadelphia Inquirer reports.

EDGE Analysis

The Phillies will be hoping they get the pitcher Rondon was with the Astros in 2018 and 2019, when he recorded a combined 3.46 ERA and 1.29 WHIP. He wasn't anything close to that guy with the Diamondbacks last year, struggling to a 7.65 ERA and 1.80 WHIP over 20 frames as his walk rate rose to 11.3 percent and his groundball rate fell to 35.5 percent. Heading into his age-33 season, a bounceback is far from guaranteed, but the risk of a minor-league deal is obviously quite low for the Phillies.

Rondon's contract option was declined by the Diamondbacks on Wednesday, Steve Gilbert of MLB.com reports.

EDGE Analysis

Rondon struggled in his first season with the Diamondbacks as he posted a 7.65 ERA and 1.80 WHIP over 20 innings across 23 relief appearances during the abbreviated 2020 campaign. The right-hander has worked as a late reliever throughout his career but may have to settle for a lower-leverage role entering his age-33 season.

Rondon allowed one hit over one scoreless inning in Friday's 6-3 win over the Astros.

EDGE Analysis

Rondon, who picked up his fourth hold in his last six outings, has turned around a dismal start and slowly trimmed an ERA that was over 10.00 as recently as Aug. 25. In his last nine appearances, the right-handed reliever's given up one run over 8.2 innings (1.04 ERA) while striking out 12. Rondon is now pitching high-leverage assignments and has his ERA down to 6.50.

Rondon allowed three runs on two hits while striking out one over one inning in Sunday's 6-1 loss to San Francisco.

EDGE Analysis

Arizona manager Torey Lovullo has yet to find the right combination of relievers to handle high-leverage innings or get games to closer Archie Bradley, and that issue came up again in this series sweep at the hands of the Giants. A day after Matt Grace let a tied game get out of hand in the eighth inning, Rondon let a one-run game escalate by surrendering a three-run homer to Alex Dickerson in the seventh inning. Rondon has allowed runs in seven of his 12 outings this year; on the whole, the one-time setup man has given up 12 runs, four home runs and six walks over 9.1 innings.

Rondon allowed one run on one hit while striking out one and recorded his first hold in Saturday's 3-2 win over the Padres.

EDGE Analysis

Rondon entered in the eighth inning with two runs of insurance and gave up one of them on a Fernando Tatis solo home run. The right-handed reliever was signed by the Diamondbacks in the offseason to be part of the setup crew, but Rondon has not delivered in 2020. He's allowed runs in four of six outings, surrendering three home runs over 4.1 innings.

Rondon allowed two runs on two hits and three walks while striking out one over two-thirds of an inning in Wednesday's 7-4 loss to the Rangers.

EDGE Analysis

Rondon and Andrew Chafin before him combined to give up five runs, the fifth time this season Arizona pitching surrendered at least three runs in an inning. Rondon is expected to be part of the setup crew, but in two appearances, he's failed twice in the late innings. He's given up four runs on four hits (one HR) and four walks over one inning.

Rondon is expected to be the setup reliever for closer Archie Bradley, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Rondon said he's not picky about about having a particular role, but he wants to know what the role is. "If you know your role, it's in your mind that you could throw the seventh or the eighth and you can prepare your body or your mind for that inning," Rondon said. "If you don't know what situation you might come in, every time the phone rings you go, 'Is it me?' and it's hard to prepare." Rondon, 32, has extensive experience in late innings, including logging 92 saves during his seven MLB seasons. RotoWire slots Bradley among a group of closers with low job security, so Rondon could work his way into a prominent role with more fantasy relevance.
