Arizona Diamondbacks vs Miami Marlins Starting Lineup — Thursday, Jun 11, 2026

Arizona Diamondbacks at Miami Marlins (2026-06-11). Merrill Kelly vs Tyler Phillips at loanDepot park.

Merrill Kelly takes the mound for Arizona, carrying a season ERA of 5.71 and a WHIP of 1.49 over 58.1 innings pitched across 10 starts. His strikeout rate stands at 5.71 K/9, while his walk rate is elevated at 3.86 BB/9, contributing to his higher WHIP. Kelly has also been susceptible to the long ball, allowing 2.01 HR/9 this season. While his trend ERA is noted as "down," his recent outings paint a volatile picture, including starts with ERAs of 9.31, 9.2, and 9.95 in April and early May, though he did post a 7.62 ERA over 7 innings in his most recent start. His blow-up rate of 33.3 percent indicates a propensity for rough outings, and he has achieved a quality start in only 33.3 percent of his appearances. For the Marlins, Tyler Phillips is listed as the starter, but his season statistics suggest a different role. Phillips has a remarkable 2.08 ERA and 1.36 WHIP over 43.1 innings, with a higher K/9 of 7.48 and a 4.57 BB/9. However, his "starts" for the season are only two, and his last five appearances show very limited innings pitched, ranging from 1.2 to 3 innings per outing, with a collective ERA of 0.84 across those relief appearances. This indicates Phillips is likely an opener or a long reliever making a spot start rather than a traditional starter expected to go deep into the game, which is further supported by his 0 percent quality start rate and 0 percent blow-up rate. The contrast between Kelly's struggles as a full-time starter and Phillips's effective but short relief work sets a dynamic tone for the initial innings.

Offensively, both teams present similar profiles. The Arizona Diamondbacks hold a team OPS of 0.696 and have scored 289 runs this season, with a batting average of 0.240. Their pitching staff, however, has a team ERA of 4.30 and a WHIP of 1.28, allowing 80 home runs. The Miami Marlins slightly edge out the Diamondbacks in hitting, posting a team OPS of 0.707 and accumulating 294 runs, with a 0.246 batting average. On the mound, Miami's pitching staff maintains a slightly better 4.18 ERA and 1.27 WHIP, having surrendered 64 home runs. Recent form shows the Diamondbacks with a 5-5 record over their last ten games, while the Marlins have performed marginally better at 6-4 in their most recent ten contests. These offensive and pitching metrics suggest a relatively even matchup in terms of overall team performance, with a slight advantage to Miami in both categories.

The head-to-head history between these two clubs from 2025 reveals a pattern of alternating dominance. The Marlins swept a three-game series against the Diamondbacks in June 2025, with scores of 6-4, 8-7, and 9-8, indicating higher-scoring affairs. Prior to that, Arizona swept Miami in April 2025, with scores of 6-4, 6-2, and 10-4. The 8.5 total line for this game appears to align with the recent higher-scoring trend observed in their matchups, particularly given Merrill Kelly's season-long struggles with a high ERA and elevated home run rate, combined with the likelihood of Tyler Phillips's short outing leading to early bullpen exposure for the Marlins.
