Left-hander Brandon Williamson (2-1, 4.35 ERA) starts for Cincinnati against Rays righty Nick Martinez (0-1, 2.45 ERA), with Tampa Bay (12-10, second in AL East) leaning on home-field edge in the dome. Reds' catching depth thins without Jose Trevino (10-day IL, back strain), while missing aces Hunter Greene (60-day IL, elbow) and Nick Lodolo (15-day IL); Rays counter infield woes with Gavin Lux (shoulder) sidelined. Bullpen freshness and lineup tweaks post-opener could sway this interleague tilt.

Left-hander Brandon Williamson (2-1, 4.35 ERA) starts for Cincinnati against Rays righty Nick Martinez (0-1, 2.45 ERA), with Tampa Bay (12-10, second in AL East) leaning on home-field edge in the dome. Reds' catching depth thins without Jose Trevino (10-day IL, back strain), while missing aces Hunter Greene (60-day IL, elbow) and Nick Lodolo (15-day IL); Rays counter infield woes with Gavin Lux (shoulder) sidelined. Bullpen freshness and lineup tweaks post-opener could sway this interleague tilt.
