Pazos was traded with shortstop Jean Segura and pitcher Juan Nicasio from the Mariners to the Phillies in exchange for first baseman Carlos Santana and shortstop J.P. Crawford on Monday, Ken Rosenthal of The Athletic reports. The southpaw was a solid piece in the Mariners' bullpen last season, producing a 2.88 ERA and 19 holds. His 8.1 K/9 left a bit to be desired, but he counteracted it with a career-best 2.7 BB/9. Pazos figures to act as the top left-handed reliever for his new team, though his relatively low strikeout rate and his 4.74 ERA away from Safeco Field last season limit his fantasy appeal.
Pazos was recalled from Triple-A Tacoma on Saturday, Ryan Divish of The Seattle Times reports. Pazos was a reliable bullpen piece for the Mariners -- 2.68 ERA and 1.17 WHIP over 40.1 innings -- but was demoted to Tacoma in mid-August as the team reshuffled its roster. The 27-year-old recorded 17 holds before he was sent down and could regain a similar role for the final month of the season.
The Mariners optioned Pazos to Triple-A Tacoma on Sunday. Pazos has been dependable this season while working in a setup role in front of closer Edwin Diaz, recording 17 holds to go with a 2.68 ERA and 1.17 WHIP in 40.1 innings. Rather than out of any dissatisfaction with Pazos' performances, the Mariners likely sent him to Triple-A strictly to clear a roster spot for Roenis Elias (triceps), who returns from the 10-day disabled list to start Sunday against the Dodgers.
Pazos earned his 16th hold in a win over the White Sox on Sunday with a scoreless one-third of an inning. He's now earned six holds and one victory over his last nine appearances. The one stumble for Pazos during that stretch was a big one, as he allowed three earned runs over two-thirds of an inning to the Rockies in Coors Field on July 13. He hasn't given up any runs otherwise in that span, helping lead to an impressive .185 BAA and .199 wOBA allowed over 7.1 innings. It's the latest example of the improvement Pazos has demonstrated this season, a campaign in which his ERA (2.43), WHIP (1.02), holds (16) and BB/9 (1.35) are all at career-best levels.
Pazos, who fired a scoreless eighth inning in which he allowed a hit and a walk in a loss to the Red Sox on Thursday, now has a 1.13 ERA over the eight innings covering his last 12 appearances. The 27-year-old southpaw has pitched to some contact (10 hits) during that span, but he's been able to limit the damage to just one earned run. Pazos currently sports a career-best 1.48 ERA and 0.99 WHIP, with both numbers representing significant improvements over last season's respective 3.86 and 1.40 figures. The considerably sharper location Pazos has demonstrated has been one of the more notable aspects of his 2018 body of work thus far, as he's lowered his BB/9 from last season's bloated 4.02 to a minuscule 0.74 over 24.1 frames.
