LIVINGSTON — Chase Sperbeck helped give the Sierra baseball team a jump start to the season Friday, and the Timberwolves needed the early run-scoring bursts as they held on for a 7-6 win over Livingston. Trailing 7-2, Livingston plated two runs in each of the final two innings before its comeback fell short. Sperbeck finished 2 for 3 with three RBIs.
