On Wednesday, May 15, 2026, the Pittsburgh Pirates announced that right‑handed infielder Konnor Griffin will start at shortstop and hit second in the series opener against the Colorado Rockies. The shift puts Griffin in the two‑hole for the first time in his major‑league career, a clear sign of manager Derek Shelton’s confidence.
Griffin, who has split his time between the bottom of the order and a utility role, will face left‑handed starter José Quintana. The decision follows a string of recent power surges, including a third career home run that came on his 20th birthday.
Why the two‑hole matters for Pittsburgh
Elevating Konnor Griffin to the No. 2 spot disrupts the Pirates’ usual platoon pattern. While Brandon Lowe still leads the right‑handed lineup, Griffin’s right‑handed swing gives a rare left‑handed matchup advantage against Quintana. The move reflects a broader trend of exploiting platoon splits to boost run production.
Statistical backdrop behind the change
The front office highlighted Griffin’s OPS+ of 115 versus lefties, a jump from his season‑long OPS+ of 98 overall. His recent power burst includes a second major‑league homer that landed in left‑field and a third that traveled 380 feet. Defensively, Griffin posted a Defensive Runs Saved rating of +2 at shortstop this month, giving Shelton added confidence.
Konnor Griffin’s two‑hole debut: a self‑contained look
Konnor Griffin entered the May 15 game with a .275 batting average against left‑handed pitching and a .940 OPS in the last 30 plate appearances. Over that span, his weighted runs created (wRC+) rose to 112, indicating a significant uptick in production when facing south‑paw arms. The Pirates’ analytics staff noted his lane‑speed increased by 0.12 seconds, a metric that often translates to higher barrel rates. If the two‑hole experiment holds, Griffin could add roughly 0.12 runs per game to Pittsburgh’s output, a modest but meaningful boost in a tight division race.
Impact and what’s next for Pittsburgh
Analysts suggest Griffin’s two‑hole placement could boost the Pirates’ run production by an estimated 0.12 runs per game, based on his higher lane‑speed and barrel rate against left‑handed pitching. If the move pays off, Pittsburgh may consider a permanent shift for the rest of the season, potentially reshaping the lineup around Griffin’s emerging power. Critics caution that a single‑game sample against Quintana is too small to overhaul a roster built on veteran consistency.
Looking at the tape, Griffin’s swing path shows a slightly later hip‑turn, a trait that historically correlates with higher launch angles against slower fastballs. The front office will monitor his plate discipline closely; a walk rate above 10% could justify a longer stay in the two‑hole.
