Pitching style

Valverde throws just two pitches, a four-seam fastball (93-96 mph) and a forkball (84-87). He throws a slightly higher percentage of forkballs to left-handed hitters. He is comfortable using the pitch in almost all counts, although he throws it most often when it is 0-2 or 1-2. Valverde's control is sometimes spotty, as he has an above average career rate of 3.9 walks per nine innings. This balances a dominating 10.3 strikeouts per nine innings ratio.

Valverde is also known for his energetic, highly emotional style on the mound. He frequently celebrates outs and saves very demonstratively. Some have questioned the sportsmanship of his behavior, including former teammate Miguel Montero of the Arizona Diamondbacks who has called him "unprofessional".
